The 5,577-square-foot apartment has a terrace that is 192 feet long

The developer of a soon-to-be-listed $39 million Upper East Side condo in New York is betting on wide appeal: The unit’s terrace spans nearly a city block.

The 5,577-square-foot, four-bedroom, 4½-bath unit is a full-floor apartment with an additional 2,440-square-foot terrace that wraps around part of the building, according to listing agent Katherine Gauthier of Douglas Elliman. From one end to the other, the terrace runs 192 feet; a typical city block is about 200 feet, according to a City Planning spokesperson.
